In a move to help growers maximize equipment and address labor shortages, Carbon Robotics launched its Carbon AutoTractor, an autonomous solution installed on existing tractors.
Carbon Robotics’ founder and CEO Paul Mikesell says its Carbon AI will power remotely monitored tractors to help specialty crop growers deploy laser weeders for almost around-the-clock production.
“With LaserWeeder, farmers want to run them as much as they possibly can, but it’s hard to find labor,” he told The Packer. “It’s really hard to find labor to do the tractor driving. It’s hard to find labor to do these late midnight shifts. It’s hard to find people to do all the different tasks you want to do with the tractors.”
The Carbon AutoTractor features two core components: the Carbon Autonomy Kit and the Remote Operations Control Center. Mikesell said operators in ROCC handle any obstructions through monitored autonomy and take over the autonomy system, so production continues. He said growers, then, don’t have to worry whether an autonomous task gets completed.
“They’re trained in using Carbon Auto Tractor,” he said. “They know how to do the functions that the farmer wants to do in the field. And then, whenever there’s something that comes up, they can literally change drive the tractor remotely, and get through whatever obstacle it is, and then keep moving.”
Mikesell said the Carbon Auto Tractor will currently work for LaserWeeder tasks, ground prep such as mulching, mowing, discing and more, but there are plans to expand its capabilities in the future.
The Carbon Autonomy Kit is initially compatible with John Deere 6R and 8R Series tractors, requiring no permanent modifications and installation completed in less than 24 hours. Once installed, tractors can toggle between autonomous and manual operation as needed.
“It bolts on and then that you plug into the harness in the inside on the inside cab, and there’s a box that mounts on the window that you can turn it on and off,” Mikesell said.
The Carbon AutoTractor system includes RTK-accurate GPS, 360-degree cameras and radar-based safety sensors, as well asphysical, remote and mobile e-stops connected via a high-speed, low-latency satellite link.
“We have better visibility from the cameras on the roof than you do from the inside the cabin,” Mikesell said.
And for those growers who might be reluctant to go to an autonomous tractor, Mikesell said the Carbon AutoTractor is designed to help growers better deploy farm labor where it’s needed most.
“You want somebody there to inspect or notice problems with your irrigation or things of that nature. You’ll still want to have those people around, but the point is that they don’t have to spend all that time driving up and down the rows to do the simple task,” he said. “They can then spend their time focusing on figuring out where or if there’s issues and how to address other problems and it relieves the constant need to be driving the tractor all the time.”
Mikesell said this solution also offers growers the option to deploy tractors at night for weeding or when the nighttime temperatures are cooler. This also helps growers maximize return on investment by being able to run the autonomous solution all the time, he said.
“We found that lot of people want to run their LaserWeeder 24/7 because they get a really good ROI or more crops they can put it under, but they just can’t find the operators to run it 24/7,” he told The Packer. “If you can run it, 24/7, you can double the hours in a typical season and you can get that tool doing everything you need it to.”
Carbon Robotics said the autonomous solution works seamlessly with its LaserWeeder, automatically adjusting speed to optimize weeding performance based on weed type, size and density, which can boost coverage by up to 20% compared to manually operated systems.
Brandon Munn, farm manager with Columbia Basin Onion, has worked with the Carbon Robotics team on this autonomous solution.
“With many of our tractors and LaserWeeders running autonomously with Carbon AutoTractor, we’re able to operate more hours, address labor challenges and make night shifts safer and more reliable,” Munn said in a news release. “This isn’t just automation; it’s a practical solution that’s fundamentally changing how we farm.”
Additional Details Come In On AutoTractor
Farm Journal talked with CEO Paul Mikesell to see what else we could learn about the system and what makes it different from other tractor autonomy kits on the market. Here’s a handful of bullet points breaking down what we uncovered:
- Don’t Call It A Retrofit - Because the AutoTractor kit doesn’t effectively alter or change anything mechanically on the tractor itself, Mikesell says he prefers to refer to it as a “augmentation kit.”
- Satellite Connectivity Changed The Game - When Mikesell and his team started this project back in 2023, connectivity was a limiting factor in enabling a tractor to safely operate with complete autonomy. That is no longer a limiting factor as developments in the stratosphere like SpaceX’s StarLink and Intellsat’s low earth orbit constellations have provided the necessary latency and bandwidth to make driver-less operation safe and viable.
- Pricing Is Still TBD - Pressed on how much the system will cost from an up-front investment standpoint, Mikesell told us that “we’re still fine tuning that price.”
- Expect An Hourly Fee - Mikesell did confirm that the technology will carry a per-hour fee. He says that fee will track closely with what the user would pay a local machine operator to run the tractor. That could mean a per-hour fee anywhere from $15 in the Midwest to upwards of $25 per hour in high-wage markets like California and Washington. “We’re trying to save you money by not having to worry about travel time out to the fields. There’s no lunch break. You don’t have to worry about paying overtime. This machine will do as many double shifts as you want, and we’re still employing people to do all the monitoring. So we have a very skilled and qualified group of people that are doing all the monitoring. So that’s kind of the model: we charge you per hour to run this machine for you and we’ll work with you on what jobs you want done and how you want it done and make sure that everything is handled appropriately.”
- Remote Operators With Tractor Experience - Mikesell says his remote operators that task and oversee the driverless tractors for farmers get a crash course in how tractors are used on your typical farm. “Just being out there in the field long enough to understand the size of things that are around you and just kind of what a field looks like and how things are laid out, makes a huge difference when you’re trying to drive remotely,” says Mikesell. “Even though you have a better view driving remotely, because you have a nice 360 degree view off the roof, having some concept and understanding about the size of things and kind of what everything looks like helps quite a bit.”
